- Twenty apparently healthy individuals of both genders (10 men and 10 women) with a mean age of 33.4±6.9 years (24 - 50 years), weight of 70.2±15.8 kg (45 - 96 kg), height of 170.4±11.5 cm (149 - 192 cm), body mass index (BMI) of 23.9±3.5 kg/m2(-1) (19.2 - 23.7 kg/m2(-1)) and percent body fat of 22.3±6.8% (8.5 - 35.0 %) volunteered for participation. The classification of the subjects in "apparently healthy" was performed by the risk stratification criteria of the American College of Sports Medicine in 1995 (interview with signs, symptoms and/or cardiopulmonary risk factors). No subject was using any medication and had no history of diagnosed cardiovascular or metabolic disease.
